You have probably been told that speed reading does not work. The scientific consensus is that forcing your eyes to move faster inevitably destroys your comprehension. That is true for neurotypical readers. However, Moussaoui et al.’s 2025 study found that reading via Rapid Serial Visual Presentation (RSVP) actually improves reading comprehension by nearly 13% for young adults with ADHD.
If you are an adult with ADHD, you have likely spent years being burned by speed-reading techniques that were never designed for your neurology. The speed-reading industry has been selling a myth for decades. They promise that if you simply suppress your inner voice, you can absorb whole paragraphs at a glance. As a result, many adults with ADHD—already fighting an uphill battle with focus—try these techniques, fail to remember a single word they read, and quietly conclude that they are the problem.
But what if the issue is not the speed, but the eye movements themselves?
The 2025 RSVP study: what the data actually says
Moussaoui, Siddiqi, Cheung, and Niemeier (2025) published a paper in the Journal of the International Neuropsychological Society looking specifically at undergraduates with ADHD. Instead of testing how fast they could read, the researchers tested what happened when they removed the need to move the eyes at all.
They tested 76 university students (38 with an ADHD diagnosis, 38 neurotypical controls) across three reading conditions. FULL presented normal text, fully visible on the screen. PACED preserved the text layout but revealed words one at a time in their usual place. RSVP flashed words one at a time in the exact centre of the screen, removing the need for eye movements entirely.
Here is what happened to their comprehension scores:
| Condition | ADHD accuracy | Control accuracy |
|---|---|---|
| FULL | 0.72 | 0.65 |
| PACED | 0.68 | 0.64 |
| RSVP | 0.77 | 0.59 |
The researchers calculated the specific advantage by comparing the RSVP condition to the two conditions that required eye movements (FULL and PACED). Young adults with ADHD saw their comprehension improve by 6.96% when they did not have to move their eyes. The control group saw their comprehension drop by 5.82% under the exact same conditions.
Combine those two shifts, and you get a relative RSVP benefit for the ADHD group of 12.78%. Let us call it 13%.
For anyone who has spent their entire academic life being told they just need to “try harder,” having a peer-reviewed paper confirm that your eyes and your brain are legitimately fighting each other is a validating moment.
Why eye movements cost you comprehension
To understand why this happens, we have to look at working memory. Barkley’s 2015 handbook on ADHD establishes that working memory deficits are a core feature of the condition in adults. Working memory is your brain’s cognitive scratchpad. It holds onto the beginning of a sentence long enough for you to understand the end of it, allowing you to string concepts together into a coherent thought.
For an ADHD brain, moving your eyes across a page of text is not a passive action. It requires constant spatial-attentional shifting. Reading becomes a demanding dual task: you are navigating the physical geography of the paragraph whilst simultaneously trying to decode the meaning of the words.
Imagine reading a dense academic paper. You reach the end of line three, but your eyes accidentally skip to line five. You drag them back, hunt for the start of line four, and try to resume. By the time you figure out where you are, your working memory has dropped the subject of the sentence to make room for the spatial coordination. It is the mental equivalent of trying to solve a complex maths problem whilst balancing on a wobble board. Every time a peripheral distraction catches your eye, the fragile tower of information collapses, and you have to start the paragraph again.
By stripping away the visual noise and flashing words in a single stationary spot, RSVP frees up precious cognitive resources. You stop spending working memory on tracking lines. You start spending it on actually understanding the text.
The opposite effect: why neurotypical readers struggled
If removing visual friction is so effective, you might assume it improves reading for everyone. The data showed exactly the opposite. Neurotypical readers actually performed worse with RSVP.
This is not a weakness in the data. It is the entire point. It proves that neurotypical brains and ADHD brains process text differently. The control group wanted to regress—to look back at previous words to clarify context. Because RSVP flashes words and immediately hides them, it prevents regressions, and their comprehension suffered as a result. The undergraduates with ADHD, however, gained more from the removal of visual distractions than they lost from the inability to look back.
Strong controls, honest limitations
What makes this 13% advantage compelling is how rigorously the researchers tested it. They checked whether the benefit was just a side effect of medication. It was not; the RSVP advantage held for both medicated and unmedicated subgroups. They checked whether it was skewed by comorbidities like anxiety or depression. It was not. They checked for gender differences, and whether the participants had convergence insufficiency, an eye-tracking issue common in ADHD. None of these factors diminished the RSVP benefit.
Of course, science is rarely perfect. Researchers are generally the first to admit it, which is refreshing in an industry that usually promises miracles.
The paper names its own limitations honestly. The study looked exclusively at a single Canadian university population. We are talking about undergraduates with ADHD, not necessarily the broader public. Only three participants had the hyperactive subtype of ADHD, meaning the results skew heavily toward inattentive and combined profiles. Furthermore, comprehension was tested with a single multiple-choice question per passage. That is a fairly blunt instrument for measuring deep semantic understanding.
According to the World Federation of ADHD International Consensus Statement (Faraone et al., 2021), adult ADHD has a worldwide prevalence of around 2.5%. It profoundly affects major life activities, including education and occupational functioning. For an adult navigating complex work documentation or returning to university, finding tools that genuinely accommodate their neurology is vital. We need larger, more diverse samples to see exactly how far this RSVP benefit extends across that broader population. As a starting point, however, it is incredibly promising.
Where this leaves ADHD readers
If you are a young adult with ADHD, this data confirms that you do not need to read like everyone else. If a wall of text feels cognitively exhausting, you are not lazy. Your working memory is simply being taxed by the act of visual navigation.
This is why we built Accruva to include Focus mode, which uses this exact RSVP technique, alongside four other reading modes. The Moussaoui study proves that whilst RSVP helps ADHD readers, it actively hinders neurotypical brains, which is exactly why a single-mode approach fails. If RSVP fits your brain today, use it. If you are reading a dense contract tomorrow and need to look back at previous sentences, you can switch to Chunking or Bold Flow when the material calls for it.
Try Focus mode for yourself
Focus mode is free on every tier, alongside four other reading modes. No trial that quietly charges you. No accessibility features locked behind Pro.

What is RSVP reading?
Rapid Serial Visual Presentation (RSVP) is a digital reading method where words are flashed one at a time in the exact same spot on a screen. It eliminates the need for your eyes to track across lines of text, removing the visual friction of a traditional page.
Who actually benefits from RSVP reading?
While often marketed to everyone as a speed-reading tool, peer-reviewed evidence such as Moussaoui et al. (2025) suggests it is particularly beneficial for undergraduates with ADHD. It reduces the working memory load required to navigate a page, allowing the brain to focus entirely on comprehension.
Why do neurotypical readers perform worse with RSVP?
Neurotypical readers rely heavily on regressions. These are small backward eye movements to re-read earlier words and clarify context. Because RSVP flashes words and disappears them, it prevents these regressions, which can hurt comprehension for brains that rely on them.
How does Accruva implement this research?
Accruva offers Focus mode, which uses the RSVP technique to help ADHD readers minimise visual distraction. However, because different brains need different tools, it sits alongside four other reading modes. You can always choose what fits your material.
Where can I read the full Moussaoui 2025 study?
The study, “Reading without eye movements: Improving reading comprehension in young adults with attention-deficit/hyperactivity disorder (ADHD),” is Open Access. It is available via the Journal of the International Neuropsychological Society or PubMed at pubmed.ncbi.nlm.nih.gov/41277242.
If your brain has been fighting you every time you tried to read, it was not you. The tools were never built for you. They are starting to be.
